I NEED YALL’S HELP 2x+12=64 Step by step

Mathematics

Answer:

2x + 12 = 64

x = 26 (mark brain if this helps and is correct)

Step-by-step explanation:

to solve equations with one missing variable we must use the order of operations of equality

step 1: use the subtraction property of equality meaning subtract each side of the equation

ex: 2x + 12 - 12 = 64 - 12   (2x = 52)

step 2: use the division property of equality meaning divide each side of the equation by 2

ex: 2x/2 = 52/2   (x = 26)

step 3: check your answer by putting 26 as x because that is our answer

2(26) + 12 = 64 (multiply 2 * 26)

52 + 12 = 64 (add 52 + 12)

64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)

A line of a slope of 8 passes through the point (-6,4). What is its equation in point slope form?
kotykmax [81]

Answer:

\huge\boxed{y-4=8(x+6)}

Step-by-step explanation:

The equation of a line in the point-slope form:

y-y_1=m(x-x_1)

m-slope\\\\(x_1;\ y_1)-point

We have:

m=8\\\\(-6;\ 4)\to x_1=-6;\ y_1=4

Substitute:

y-4=8(x-(-6))\\\\y-4=8(x+6)
